LI Jun, HE Xi-ping, ZHANG Feng, et al. Parameters calculation of acoustical matching layers of ultrasonic transducers[J]. 2008, 27(12): 106-108. DOI: 10.13873/j.1000-97872008.12.007.
The transmission coefficients of longitudinal vibration ultrasonic transducers are studied.The multi-group optimum matching thicknesses are given according to calculation.Once the glue is taken as the first matching layer
the specific material of the second layer can easily be found.The result shows that the parameters of the cohesive glue and matching layers have a great impact on the transmission coefficients.The parameters of each matching layer are accurately calculated and an optimum solution to the impedance match between a PZT transducer and a water load is also proposed
which is useful to the actual designing of matching layer.
